Modeling of a Machine Tools Spindle using a Hybrid Model

Popis výsledku v původním jazyce

The paper describes modeling of machine tools spindle using a hybrid model. The model connects the FEM modelling and analytical methods together. The spindle geometry is created and then meshed in FEM (using software Ansys and programming language APDL).The mesh is reduced and mass and stiffness matrices are exported. The exported matrices are imported into Matlab. Then the analytical model of bearings is joined in Matlab. The model of bearing describes bearing stiffness in dependence on outer bearingdeformations. Damping ratios are obtained from the statistical evaluation of lot of the experimental measurements. The modal properties and the transfer functions of damped system are computed. Verification of the model is shown. As shown, the model is useful for cutting stability prediction or spindle geometry tuning.
